One in 7 of all humans on Earth logged onto Facebook in a single day.
It’s been described as an important milestone by Facebook founder Mark Zuckerberg after being reached on Monday 24 August 2015.
In a Facebook post, Mr Zuckerberg said he was proud of the Facebook community for what it had achieved and that it was only the start of connecting the world
“I’m so proud of our community for the progress we’ve made. Our community stands for giving every person a voice, for promoting understanding and for including everyone in the opportunities of our modern world.
“A more open and connected world is a better world. It brings stronger relationships with those you love, a stronger economy with more opportunities, and a stronger society that reflects all of our values,” he said.
“Thank you for being part of our community and for everything you’ve done to help us reach this milestone. I’m looking forward to seeing what we accomplish together.”
